This is what the HPE1200 Hennessey Corvette ZR1 is like on the road.
Last we saw the HPE1200 Corvette ZR1, Hennessey was proving its might at the drag strip by running under 9 seconds in the quarter-mile. Sure, that was on a prepped surface with drag radials, but that’s still a ridiculously fast time. Especially considering it was over 100 degrees in the Texas heat of the summer.
But what about how the HPE1200 is as a daily driver? Well, for that, we can see how this thing rolls on Hennessey’s test track. And pretty much as you’d expect, the car is still ludicrously fast, but in a more mundane kind of way. It’s the kind of speed that comes from accidentally pressing the accelerator a little too hard and finding yourself at 150 mph. Y’know, the little “whoopsie” that would really only be safe on a closed test track.
Hennessey's spokesperson emphasizes not just the car's immense power but also how easy it is for Hennessey to perform just a few tweaks to the stock car to produce so much power. It's still the same engine, but with new pulleys, throttle body, a custom camshaft, ported cylinder heads, new valves and springs, upgraded intake and exhaust valves, and a strengthened 8-speed automatic transmission. It also still uses the stock supercharger, although it's also been modified for extra power.
There's also new pushrods, stainless steel headers, high-flow catalytic converters, and tuning to accept racing fuel instead of regular unleaded. Which is about as far away from stock as you can get without actually swapping engines.
On the plus side, you wind up with a Corvette that has more power than a Demon and is faster than one too, albeit one without much of the Demon’s drag race-specific technology. It would take an awfully experienced driver to get below 9 seconds in this beast without having it veer into a retaining wall.
Hennessey notes that while the C7 is superb, they’ve got plans for the upcoming C8. Big plans. And if you want in on that action, you’d better sign up fast. So far, over 50 people have decided to take their new 2020 Corvette Stingray to Hennessey for some extra oomph that Chevy won’t provide for a year or more. Best sign up soon as slots are filling fast.
